I used a proportional-width typeface on one of my recent projects in Java. It felt quite natural, actually, and took some of the pointless formatting distractions away from the coding process. Didn't constantly think about trying to keep lines of code within 80 characters, for example -- if it was readable on my screen it was fine. The drawbacks were things like confusing lowercase L with 1 (one) in the sans-serif font I preferred, or the sort of editing where I was trying to change stuff at, say, character position 67 in a series of lines. It seems better for writing code than for editing it. Definitely give it a try if you haven't yet.
